[PATCH 0/3] arm64: entry: Convert to generic entry

From: Jinjie Ruan
Date: Tue Jun 25 2024 - 05:25:17 EST


Currently, x86, Riscv, Loongarch use the generic entry. Convert arm64
to use the generic entry infrastructure from kernel/entry/*. The generic
entry makes maintainers' work easier and codes more elegant, which aslo
removed a lot of duplicate code.

entry: Add some arch funcs to support arm64 to use generic entry
arm64: Prepare to switch to generic entry
arm64: entry: Convert to generic entry
